Once the renovation was complete, the apartment was rented out for 4,100 PLN per month plus around 450 PLN of service charge. Annual rental income comes to 49,200 PLN, not including the service charges paid separately by the tenant.
The full cost of purchase, renovation, equipment and basic transaction costs came to around 814,000 PLN, which means a gross yield of around 6% per year.
Beyond rental income, the renovation itself created a measurable increase in market value. Based on comparable renovated, turnkey units in the same micro-location, the apartment's estimated market value after renovation is around 920,000 PLN — roughly 21,395 PLN/m². That sits well above Wola's district-wide average of around 17,572 PLN/m² for mostly unrenovated secondary-market stock (see our Wola property guide and our comparison of the best districts in Warsaw for property investment), which reflects the full renovation, made-to-measure furnishing and rental-ready condition rather than the district average alone.
Against the full invested cost of around 814,000 PLN, that implies an estimated unrealised capital gain of around 106,000 PLN on top of the ~6% gross rental yield — a combined return that sits above what a buy-and-hold strategy on unrenovated stock in the district would typically deliver.
This also tracks the broader direction of the Warsaw market. According to the National Bank of Poland's quarterly BaRN residential price data, secondary-market apartment prices in Warsaw rose by around 50.7% over the past five years, with new-build transaction prices up around 54.5% over the same period and around 115.7% over ten years (NBP data, compiled by Deweloperuch.pl). More recently the market has cooled: NBP's preliminary Q1 2026 data puts Warsaw's average secondary-market transaction price at around 16,393 PLN/m², down about 1.7% year-on-year, while new-build transaction prices held broadly flat at 16,475 PLN/m² (+0.2% y/y) (NBP BaRN, via OnGeo.pl). For buyers, that combination — strong multi-year appreciation against a currently flat-to-soft short-term market — supports a long-hold strategy over short-term flipping.
